Abstract

A new sandwich cathode design is provided having a first cathode structure of a first cathode active material of a relatively low energy density but of a relatively high rate capability, for example SVO, mixed with a second cathode active material having a relatively high energy density but a relatively low rate capability, for example CFx, with the percentage of SVO being less than that of CFx and sandwiched between two current collectors. Then, a second cathode mixture of SVO and CFx active materials is contacted to the outside of the current collectors. However, the percentage of SVO to CFx is greater in the second structure than in the first. Such an exemplary cathode design might look like:
   (100-y)% SVO + y% CFx, wherein 0 ≤ y ≤ 100/current collector/(100-x)% SVO + x% CFx, wherein 0 ≤ x ≤ 100/current collector/(100-y)% SVO + y% CFx, wherein 0 ≤ y ≤ 100, and wherein the ratio of x to y is selected from the group consisting of y < x, x < y and x = y.
